Insufficient system resources exist to complete this operation

We've had a number of instances recently of users receiving errors when trying to access various file servers across various sites of "insufficient system resources exist to complete the opeation"

In a single instance, I've had this on my home network, and was resolved by modifying a registry key (IRPStack seems to ring a bell) but it is a concern that it seems to be occuring a number of times across different sites for different servers and clients in the last few days. Nothing detected by our AV/malware scanners, but I am suspicious......

Do you use Symantec? If so which version?
monitor all processes for paged pool usage and non-paged pool usage.

These pools are limited blocks of memory which can get used up. When this happens you get the issue you're seeing.

Have you recently updated drivers? enabled scalable networking (TCP chimney? checksum processing?) installed new management apps? Antivirus updates are a definite possibility. these are all things to bear in mind.

If any of the affected servers are 2008, you could check out the reliability monitor. This should show you the incidence of server reboots, and any installs that happened shortly before the issue started are good candidates for checking out.

As far as I know there have been no recent updates. The majority of file servers remain SAV10, clients are a mix of SAV10 and SEP11...I'm getting our regional guys to check the servers out, just there's a concern of viral activity what with the number of machines picking up the same issue at a similar time....

We started seeing it in a few instances with SEP11..... Once you get the message, the local client couldnt do ANY command, as the operation couldnt be done. Disabling teh WIFI cards in some models were able to be enough that the systems recovered. Overall, those instances were tied to a driver problem, where the Paged Pool limits were being hit, and of course the resources werent available yadda yadda yadda......

Are the models on the clients consistent, or are they various makes/models?

PS,

IRPStackSize is no longer an issue (i believe from 2000 SP3, but I could be mistaken)

OK, I've just picked up an email from a user who had a prompt asking for the location of Symantec Antivirus.msi

Trying to launch VPC32.exe (SAV10) produced an Application Error (memory could not be read) and also a Bad Image error

Trying to launch appwiz.cpl via Run also produced Application Error (memory again)

Unable to access \\server\vphome\clt-inst\win32\ to access install files - Insufficient system resources exist to complete this operation.

Look for error 53 in event viewer.
